A Pretender put quite simply
is a genius who has the ability to become literally anyone or anything he or
she wants to be.
For example, a Pretender can read a book on heart surgery a short time
before going into an operating room to perform a flawless heart
Pretenders can simulate all sorts of real life situations but unlike
computers, they add the element of human emotion because they're able
to imagine themselves in the shoes of whoever they're pretending to be.

who of the Pretender universe"...
